Despite that, some benefits of CBD for paranoia and related disorders have been observed anecdotally.
Is CBD an antipsychotic?
However, there is insufficient evidence to prove that CBD could affect brain function in people with schizophrenia. Research does not suggest or support use of medical cannabis as a treatment for such people.
Can CBD oil replace antipsychotics?
The first of the CBD schizophrenia clinical trials was conducted in 1995. The study subject was a 19-year-old female. The researchers gave her 1,500 milligrams of CBD every day for four weeks. They found that it improved her acute psychotic symptoms.
The study included a group of 13 people with a diagnosis of psychosis and 16 people without the disorder. The participants were asked to perform three different verbal-association memory tasks (such as deciding whether words were paired in a logical way, and recalling which words they’d previously seen paired, or what font they were in) while in an fMRI machine.
These results add to a growing body of research into the ways CBD may offer a treatment for different psychiatric conditions. The need is great: Current gold-standard treatments tend to work only in a subset of people and can have serious side effects when taken over the long term. CBD may be easier for the body to process, making it a more tolerable long-term option for people with chronic mental health conditions, Bhattacharyya says.
The results provide insight into which part of the brain is affected by CBD and suggest CBD may curb symptoms of psychosis in the human brain.
CBD and brain activity
Ultimately, the study sample is too small to draw definite conclusions on CBD as a treatment for psychosis patients as a group. The study also doesn’t look at how brain activity changes matched up to behavior in the participants with psychosis — which means we can’t know if CBD improved their performance on the memory tasks.
The single dose of CBD appeared to diminish the differences in activity in the brains with psychosis and those without. For example, during memory exercises like recalling something verbally, a brain affected by psychosis has abnormal activity such as greater connectivity in the front of the brain (prefrontal, mediotemporal and striatal areas), which makes it harder to recall things logically. But after taking even just a single dose of CBD activation in these areas tended to look similar to that of a person without the condition.
Can CBD treat psychosis?
Scientists compared brain scan results of people with a diagnosis of psychosis and people without the disorder as they were doing a memory exercise. In the people with psychosis, the researchers found clear differences in the activity patterns in their prefrontal, mediotemporal, and striatal areas of the brain — those that regulate decision making, learning and memory. But when these participants were given a single dose of CBD, their brain activity patterns were more similar to those of people without the disorder.
“This study is essentially showing how CBD might work, and which effects might underlie symptoms of psychosis,” he says. “But we seldom treat psychosis giving single doses; we have to give doses for various weeks before seeing clinical, meaningful results.”
The data on cannabidiol (CBD) for schizophrenia is plentiful, consisting of both animal and human research. Unlike many other condition, there is also a solid body of evidence coming from human clinical trials and double-blind controlled randomized studies.
Schizophrenia is a complex brain disorder with this complexity helping to explain why there are o many misconceptions about the disease. Most people with schizophrenia are not dangerous or violent, do not suffer from dissociate personality disorder and do not have to live in hospitals. With the correct treatment to manage symptoms, most people with schizophrenia allows them to perform as high-functioning individuals that hold jobs, have families of their own and play active roles in their communities.

From the evidence, they concluded that CBD has potential as an effective antipsychotic treatment and that CBD is capable of modulating psychosis like behaviors in both dopaminergic and glutamatergic animal models of psychosis. In addition, the data suggests that the vanilloid (TRPV1) receptor is also likely to play an important role in CBD action. Similarly, imaging studies provided various clues on a potential antipsychotic effect of CBD while biological models explain the potential antipsychotic effects of CBD. The latter ranges from interference with endocannabinoid system (ECS) functioning by inhibition of FAAH activity, to immunological properties of CBD that might moderate immunological processes involved in the pathophysiology of psychotic disorders.
